Comparative behavior of gasoline–diesel/butanol–diesel blends and injection strategy management on performance and emissions of a light duty diesel engine

Biodiesel or oxygenated fuel from renewable sources set a challenge to the engine technology to design relevant systems for keeping high efficiency and low environmental impact. The objective of this paper was to investigate the influence on combustion and emissions in a Euro 5 light duty diesel engine fueled with gasoline–diesel, butanol–diesel and commercial diesel fuels. Engine tests were carried out 2500 rpm and 0.8 MPa of brake mean effective pressure. The investigation was focused on the management of injection strategy for different combustion phasing under two oxygen concentrations at intake.
